BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to the use of a combination of a sugar alcohol and D-tagatose in a variety of zero- or low-calorie beverages and food products. This invention particularly relates to a method of improving the taste of zero- or low-calorie beverages and food products, i.e., achieving a taste similar to that of a full-calorie beverage or food product, by including a blend of non-nutritive sweeteners, a sugar alcohol and D-tagatose in a zero- or low-calorie beverage or food product. This invention also particularly relates to the use of a combination of a sugar alcohol and D-tagatose to achieve a high quality zero- or low-calorie frozen carbonated beverage. This invention further relates to beverages and food products which include both a sugar alcohol and D-tagatose.

2. Related Background Art

Zero- or low-calorie beverages and food products are very popular. Such diet products typically contain, singularly or in blends, non-nutritive sweeteners such as aspartame, acesulfame-K, saccharin, sucralose and cyclamate. While consumers do not have to worry about calories, non-nutritive sweeteners are known to impart a taste different from that of full-calorie counterparts. So-called “diet taste” is commonly described as slow onset but lingering sweetness accompanied with a bitter and/or metallic undesirable aftertaste and a watery mouthfeel. Due to the greatly reduced sugar solid content, diet drinks also lack the body and/or thickness perception associated with full-calorie drinks. G. R. Shore, et al., “Taste and Mouthfeel in Low Calorie Soft Drinks”, Contribution of Low- and Non-Volatile Materials to the Flavor of Foods, W. Pickenhagen, ed., Allured Publishing Corp., pp. 119-123 (1996).

Zero- or low-calorie beverages and food products with tastes similar to those of full-calorie products are very desirable and have been sought after for quite some time. Currently, however, methods of improving taste have fallen short of achieving a taste similar to full-calorie products.

One option is to blend non-nutritive sweeteners. Many blends (e.g., aspartame and acesulfame-K) impart a higher degree of sweetness than individual sweeteners on an equal concentration basis. This synergistic effect results in sparing the amount of sweetener used in a given application and is therefore referred to as quantitative synergy. Blending also causes another kind of synergy, referred to as qualitative synergy, because the taste quality of the blend often is more rounded and of less bitter/metallic off-taste.

The beverage industry has taken advantage of these synergies and marketed many diet colas containing sweetener blends. “Blending the Taste Sensation”, Liquid Foods Int'l., vol. 3, no. 1, p. 31 (1999). For example, PepsiONE® (aspartame/acesulfame-K), Coke Light® (aspartame/acesulfame-K or sodium cyclamate/acesulfame-K/aspartame) and Diet Rite Cola® (sucralose/acesulfame-K) all contain sweetener blends. Sweetener blending can also enhance the shelf-life of diet cola, especially in cases where aspartame is used as a key sweetener. For example, most soda fountain diet colas in the United States contain aspartame, acesulfame-K, and sodium saccharin. When aspartame degrades, the other two stable sweeteners maintain a certain degree of sweet taste.

Another option is to include flavor enhancing additives. A myriad of such flavor enhancing additives have been identified to date. U.S. Pat. Nos. 4,902,525 and 6,066,345, JPA 7-274829 and EP 0 759 273 relate to the addition of erythritol to beverages for purposes of flavor enhancement. Additionally, D-tagatose is known to produce improved flavor and mouthfeel at low doses with combinations of intense sweeteners.

Efforts in the beverage industry in the United States and abroad have produced taste-improved diet products. To date, however, there is simply no effective method of significantly improving the taste of zero- or low-calorie beverages and food products, i.e., achieving a taste similar or identical to that of full-calorie beverages and food products.

In addition, further problems arise when attempting to achieve zero- or low-calorie frozen carbonated beverages (FCBs), which are semi-frozen carbonated drinks dispensed from a FCB dispenser. Such beverages require bulk solutes to stabilize small ice crystals and to trap carbon dioxide for a good taste and a smooth texture. The most commonly employed bulk solute is sugar. However, sugar is caloric and is therefore not suitable for the formulation of zero- or low-calorie FCBs. Sugar alcohols, which are known to mimic the bulk properties of ordinary sugars and have fewer calories, also are less sweet and most have undesirable gastrointestinal effects when ingested at comparable levels to sugars. Thus, making diet FCBs has been very difficult due to the need for both bulk solutes and zero or low calories.

DETAILED DESCRIPTION

As used herein, “taste” refers to a combination of sweetness perception, temporal effects of sweetness perception, i.e., on-set and duration, off-tastes, e.g., bitterness and metallic taste, residual perception (aftertaste) and tactile perception, e.g., body and thickness. As used herein, “zero-calorie” means having less than 5 calories per serving, e.g., per 8 oz. for beverages. As used herein, “low-calorie” means having less than or equal to 40 calories per serving, e.g., per 8 oz. for beverages. As used herein, “diet” refers to either “zero-calorie” or “low-calorie”. What is more, “reduced calorie” means having a reduced number of calories as compared with a full-calorie counterpart; more particularly, “reduced calorie” typically means having at least a 25% reduction in calories per serving, e.g., per 8 oz. for beverages.

The present invention is first directed to a method of improving the taste of diet beverages and food products. According to the present invention, it is possible to achieve a diet beverage or food product with a taste that is substantially similar or identical to that of a full-calorie beverage or food product. As a result of the present inventive method and, in particular, the combination of sweetener or sweetener blend, sugar alcohol and D-tagatose, overall sweetness, aftertaste duration, mouthfeel and sucrose-like quality of diet foods and beverages are unexpectedly and advantageously improved.

According to the first embodiment of the present invention, the taste of a diet beverage is improved by including in the beverage (a) at least one non-nutritive sweetener, (b) a sugar alcohol and (c) D-tagatose. Beverages include, without limitation, carbonated soft drinks, fountain beverages, frozen ready-to-drink beverages, coffee beverages, tea beverages, powdered soft drinks, as well as liquid concentrates, flavored waters, enhanced waters, fruit juice and fruit juice flavored drinks, sport drinks and alcoholic products. The beverage may be carbonated or noncarbonated. In a preferred embodiment of the present invention, the beverage is a carbonated cola-flavored soft drink or a frozen carbonated beverage (FCB).

While it is believed that the combination of a single non-nutritive sweetener, a sugar alcohol and D-tagatose would lead to improved taste, it is also believed that the improvement is much more pronounced when using a blend of non-nutritive sweeteners. Therefore, a preferred embodiment of the present invention is directed to a method in which a blend of non-nutritive sweeteners is employed. The blend of non-nutritive sweeteners lends qualitative synergy to the taste of a low-calorie beverage in which it is included. Any blend of non-nutritive sweeteners can be employed in the present invention; two-, three-, four- and five-way blends of non-nutritive sweeteners are preferred.

Non-nutritive sweeteners suitable for use in the present invention include, without limitation, aspartame, acesulfame salts such as acesulfame-K, saccharins (e.g., sodium and calcium salts), cyclamates (e.g., sodium and calcium salts), sucralose, alitame, neotame, steviosides, glycyrrhizin, Lo Han Guo, neohesperidin dihydrochalcone, monatin, and protein sweeteners such as thaumatin, monellin and brazzein. Any natural or artificial non-nutritive sweetener can be employed for present purposes. As used herein, a “non-nutritive” sweetener is one which does not provide significant caloric content in typical usage amounts, i.e., less than about 1 calorie per serving (8 oz. for beverages).

Preferred two-way blends include aspartame/acesulfame-K, sodium saccharin/sodium cyclamate and sucralose/acesulfame-K. Preferred three-way blends include aspartame/acesulfame-K/sodium saccharin, aspartame/acesulfame-K/sucralose, aspartame/acesulfame-K/sodium cyclamate, aspartame/sodium saccharin/sucralose, sucralose/sodium saccharin/sodium cyclamate and acesulfame-K/sodium cyclamate/sucralose. Preferred four-way blends include aspartame/acesulfame-K/sodium saccharin/sodium cyclamate, acesulfame-K/sodium saccharin/sodium cyclamate/sucralose, aspartame/acesulfame-K/sodium cyclamate/sucralose and aspartame/acesulfame-K/sodium saccharin/sucralose. Preferred five-way blends include aspartatme/acesulfame-K/sodium saccharin/sodium cyclamate/sucralose.

One of ordinary skill in this art will readily appreciate that non-nutritive sweeteners may be combined in various ratios to form a non-nutritive sweetener blend suitable for use in the present invention. Precise ratios of non-nutritive sweeteners depend on the combination of sweeteners used in a given blend and the desired overall sweetness for a given application. Appropriate ratios can be readily determined by one of ordinary skill in this art.

One of ordinary skill in this art will also readily appreciate that the amount of the blend of non-nutritive sweeteners in a finished beverage will vary depending on a variety of factors such as the desired overall sweetness for a given application. Appropriate amounts can be readily determined by one of ordinary skill in this art.

In addition to the non-nutritive sweetener or sweetener blend, a sugar alcohol is included in a diet beverage in order to improve the overall taste. The use of a sugar alcohol blocks the lingering sweetness and the bitter/metallic aftertaste associated with the use of non-nutritive sweeteners. Sugar alcohols suitable for use in the present invention include, without limitation, sorbitol, mannitol, lactitol, maltitol, xylitol, erythritol and combinations thereof. Typically, the sugar alcohol is included in an amount from about 0.1% to 3.5% of the finished beverage by weight. Erythritol, i.e., meso-erythritol, is especially preferred for use in the present invention. Typically, erythritol is included in an amount from about 0.1% to 3.5% of the finished beverage by weight, preferably from about 0.2% to 2.5% of the finished beverage by weight.

D-tagatose is also included in the diet beverage in order to improve the overall taste. The use of D-tagatose enhances mouthfeel (also referred to as body, thickness or delocalization of sweetness). D-tagatose is included in an amount from about 0.1% to 1.0% of the finished beverage by weight, preferably 0.2% to 0.9% of the finished beverage by weight, and most preferably 0.3% to 0.6% of the finished beverage by weight.

The non-nutritive sweetener or sweetener blend provides no appreciative caloric content to a diet beverage. Based on the use level of both the sugar alcohol and the D-tagatose in the present invention, use of these ingredients does not have a significant impact on the total caloric content of a beverage sweetened as set forth in the present invention. For example, erythritol, a 4-carbon sugar alcohol, which can be obtained from Cerestar (Hammond, Ind.), is reported to generate almost no calories (0.2 calorie/g). D-tagatose, which can be obtained from Arla Foods (Union, N.J.), is reported to impart about 1.5 calories/g. It should be noted that both erythritol and D-tagatose do impart a certain degree of sweetness to the overall beverage.

Another embodiment of the present invention is directed to improving the taste of a diet food product by including in the food product (a) at least one non-nutritive sweetener, (b) a sugar alcohol and (c) D-tagatose. Again, a preferred embodiment contemplates the use of a blend of non-nutritive sweeteners. Such food products include, without limitation, confections, dairy products, gelatins, puddings, cake mixes, cereals and cereal-based products and baked goods. In a preferred embodiment of the present invention, the food product is a gelatin dessert. All of the above discussion related to the inclusion of a non-nutritive sweetener blend, sugar alcohol and D-tagatose in a diet beverage is applicable to diet food products.

Additional embodiments of the present invention are directed to diet beverages and food products which include (a) at least one and preferably a blend of non-nutritive sweeteners, (b) a sugar alcohol and (c) D-tagatose as set forth above. A preferred embodiment is directed to a diet frozen carbonated beverage (FCB). Yet another embodiment is directed to a method of making such a FCB.

Another embodiment of the present invention is directed to a sweetener composition comprising (a) at least one and preferably a blend of non-nutritive sweeteners, (b) a sugar alcohol and (c) D-tagatose as set forth above.

It is possible to include any other ingredients typically used in diet beverages and food products in appropriate amounts in the diet beverages and food products of the present invention. For example, in the diet frozen carbonated beverages of the present invention, it is possible to include other ingredients typically found in such beverages. Such other ingredients include, without limitation, acidulants, flavors, soluble low-calorie fibers such as polydextrose, Fibersol®, or arabinogalactan, chitosan, chitin, xanthan, pectin, cellulosics, konjac, gum arabic, modified starch, soy fiber, inulin, inulose, hydrolyzed guar, guar gum, beta-glucan, carageenan, locust bean gum, alginate, polyglycol alginate, foam stabilizing agents such as yucca or yucca/quillaia extracts, salts such as sodium, calcium and potassium chlorides, food grade surfactants such as monoglycerides, diglycerides, lecithin and fractions thereof, and synthetic surfactants such as Tweens®, Spans®, diacetyltartaric esters, citric acid esters, etc.

It is additionally possible to include in a beverage or food product, a combination of at least one non-nutritive sweetener, a sugar alcohol, D-tagatose and at least one nutritive sweetener in order to achieve good tasting, diet or reduced calorie beverages or food products. Any nutritive sweetener is suitable for use; as used herein, a “nutritive” sweetener is one which provides significant caloric content in typical usage amounts, i.e., more than about 1 calorie per serving (8 oz. for beverages). Such sweeteners include, without limitation, fructose, sucrose, dextrose, maltose, trehalose, rhamnose, corn syrups and fructo-oligosaccharides. All of the above discussion related to the inclusion of a non-nutritive sweetener blend, sugar alcohol and D-tagatose in a diet beverage is applicable to reduced calorie products.

The examples which follow are intended as an illustration of certain preferred embodiments of the invention, and no limitation of the invention is implied.

COMPARATIVE EXAMPLES 3A-3C

Cola drinks were prepared in the same manner as in Example 3, except insofar as erythritol (3A), D-tagatose (3B), and both erythritol and D-tagatose (3C) were omitted, respectively. Drinks were evaluated by a panel of experts in cola taste. Drinks made according to these comparative examples were judged as failing to provide a taste extremely close to that of a regular or full-calorie cola drink control, i.e., the drinks exhibited “diet taste”.

EXAMPLE 16

To a gallon of unsweetened Diet Mountain Dew® base, erythritol (2.5% by weight of finished drink) and D-tagatose (0.9% by weight of finished drink) were added, and the solution was stirred until complete dissolution occurred. Aspartame (400 ppm per finished drink) was then added, and again the solution was stirred until complete dissolution. The syrup thus prepared was placed into a frozen carbonated beverage machine (Cornelius, V3, Wisconsin) in a 1 plus 5 throw (1 part syrup with 5 parts carbonated water). The resulting FCB has good carbon dioxide overrun, smooth, creamy mouthfeel and great taste. In addition, the syrup can be successively run through the FCB machine to consistently achieve a high quality FCB.

EXAMPLE 17

To a gallon of unsweetened Diet Mountain Dew(® base, erythritol (2.5% by weight of finished drink) and D-tagatose (0.9% by weight of finished drink) were added, and the solution was stirred until complete dissolution occurred. Acesulfame-K (60 ppm per finished drink) and sucralose (60 ppm per finished drink) were then added, and again the solution was stirred until complete dissolution. The syrup thus prepared was placed into a frozen carbonated beverage machine (Cornelius, V3, Wisconsin) in a 1 plus 5 throw (1 part syrup with 5 parts carbonated water). The resulting FCB has good carbon dioxide overrun, smooth, creamy mouthfeel and great taste. In addition, the syrup can be successively run through the FCB machine to consistently achieve a high quality FCB.

COMPARATIVE EXAMPLE 4

To a gallon of unsweetened Diet Mountain Dew(& base, erythritol (3.4% by weight of finished drink) was added, and the solution was stirred until complete dissolution occurred. Aspartame (400 ppm per finished drink) was then added, and again the solution was stirred until complete dissolution. The syrup thus prepared was placed into a frozen carbonated beverage machine (Cornelius, V3, Wisconsin) in a 1 plus 5 throw (1 part syrup with 5 parts carbonated water). The resulting FCB has good carbon dioxide overrun, mouthfeel and taste. However, a good quality FCB is not consistently achieved upon successive run through of the syrup thus prepared; after a second or third run through, the nozzle chamber freezes and/or other problems arise which prevent FCB from being dispensed from the FCB machine.

EXAMPLE 18

A frozen carbonated beverage was prepared in the same manner as in Example 17 except insofar as 2.0% fructose based on finished beverage weight was also included in the FCB. Drinks made according to this example were judged as providing a taste extremely close to that of a regular or full-calore FCB conrol.

Other variations and modifications of this invention will be obvious to those skilled in this art. This invention is not to be limited except as set forth in the following claims.
